 Expansion and Innovation

County Line Road Corridor Revitalization

NOVEMBER 2005 – Waggoner partnered with the City of Ridgeland to tackle one of the region’s most congested commercial corridors. Instead of expanding lanes, the team implemented a counterintuitive yet transformative strategy: reducing the number of lanes and adding landscaping. This approach resulted in safer travel, smoother traffic, and renewed economic energy for a major retail hub. The project was later awarded the ACEC-MS 2007 Grand Award.

Coastal Highway LA 1 Mega Project

2003 – Waggoner was engaged as a subconsultant for Phase 1 of a multi-segment mega project to add 17 miles of tolled bridge on a new alignment through coastal Louisiana. The firm provided line and grade study, roadway, bridge, and coastal restoration design, permitting and construction support for the segment between Fourchon and Leeville. Waggoner later continued as a prime consultant for Phase 2 permitting for the segment between Golden Meadow and Leeville.

DeSoto County Regional Wastewater Program

1998 – Faced with a combination of environmentally impaired streams and rapid population growth, DeSoto County partnered with Waggoner to launch a strategic program with master planning. The early formation of the DeSoto County Regional Utility Authority (DCRUA) made DeSoto the first county in Mississippi to implement a consolidated wastewater system. DCRUA retained Waggoner to further advance this long-term, transformational program.
